For this case we have the following equation:
y = 100 - 8.9x
Where,
x = the number of hours of use
For 11 hours of use we have x = 11.
Substituting:
y = 100 - 8.9 * (11)
y = 2.1%
Answer:
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
y = 2.1%
Answer:
<u>The correct answer is A. -1.69</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mean of the popping time of the kernels in a brand of microwave popcorn = 150 seconds
Standard deviation of the popping time of the kernels in a brand of microwave popcorn = 13 seconds
Time that first kernel pops = 128 seconds
2. What is the z-score of this kernel? Round your answer to two decimal places.
z-score = (Time that first kernel pops - Mean of the popping time)/Standard deviation of the popping time
Replacing with the real values, we have:
z-score = (128 - 150)/13
z-score = -22/13
<u>z-score = - 1.69</u>
<u>The correct answer is A. -1.69</u>
Answer:
$198
Step-by-step explanation:
Given that:
Sales price on the sales receipt (including the sales tax) = $211.86
Sales tax = 7%
To find:
The cost of the bicycle without the sales tax = ?
Solution:
First of all, we will have to let the cost of bicycle without the sales tax.
Let the cost of bicycle without the sales tax = $
Cost of bicycle without the sales tax and with sales tax is given as equal to $211.86.
Writing the equation as per question statement:
Therefore, the cost of bicycle without the sales tax = <em>$198</em>
Answer:
This is the distributive property of multiplication.
